scipy.optimize.curve_fit?Which of the following is the correct syntax to fit a model using scipy.optimize.curve_fit?
easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Recall correct function usage
The functioncurve_fitreturns two outputs: parameters and covariance, called aspopt, pcov = curve_fit(model_func, xdata, ydata).Step 2: Check argument order and assignment
The model function is first, then xdata and ydata; assignment is to two variables, not reversed or misordered.Final Answer:
popt, pcov = curve_fit(model_func, xdata, ydata) -> Option BQuick Check:
Correct syntax = D [OK]
Quick Trick: curve_fit returns parameters, covariance in that order [OK]
Common Mistakes:
- Swapping xdata and ydata arguments
- Assigning curve_fit call incorrectly
- Misplacing model function argument
